[12-01-13 13:48]: Yesterday I installed oS 13.1 and it went smooth. I was afraid of it because of the missing fglrx for my config - that is why I skipped oS 12.3, more precisely, went back 12.2 after a day's usage. I have an old ATI Radeon HD 4730 (RV770) video card. Now the fan is less loud than it was in 12.3, but noisy compared to the fglrx driver used in 12 2. Now I read an X.org page (http://www.x.org/wiki/RadeonFeature/) and found the following line
Select the profile by echoing the selected profile to /sys/class/drm/card0/device/power_profile.
What does that mean and how to do it? Now the profile is 'default' but I think 'mid' or 'low' would be sufficient for me. There is mostly text on my screen, no games at all.
echo <selected-profile> > /sys/class/drm/card0/device/power_profile
replace "<selected-profile>" with your selected profile
My desktop system has no .../power_profile but does have /sys/class/drm/card0/device/power/... My laptop has nvidia and does not have .../drm/....
I cannot verify that the advice you read is accurate for *your* system as I have no ATI systems.
gud luk,
Thanks for the hint. I have the file structure cited in the wiki. Unfortunately it is not clear for me, when and where this echoing should be done? Should I boot to runlevel 3, do the echoing and go on with booting to X? Albert
